   - Add notification templates

4. **Week 4**: Testing and Integration
   - Write unit tests for insights
   - Write integration tests for notifications
   - Update dashboards to use insights
   - Documentation

**Quick Demo**:
```python
# examples/persona_insights_demo.py

from openfinops.insights import InsightEngine
from openfinops.observability import ObservabilityHub, CostObservatory

hub = ObservabilityHub()
cost_obs = CostObservatory()
insight_engine = InsightEngine(hub=hub, cost_obs=cost_obs)

# Generate CFO insights
cfo_insights = insight_engine.generate_insights(persona="cfo", time_range="30d")

for insight in cfo_insights:
    print(f"📊 {insight.title}")
    print(f"   {insight.description}")
    print(f"   Impact: {insight.impact}")
    print(f"   Recommended Action: {insight.recommendation}")
    print()

# Output:
# 📊 Cloud Spend Efficiency Improving
#    Cloud spend increased 15% but revenue per customer improved 22%
#    Impact: Positive - Better unit economics
#    Recommended Action: Continue current optimization efforts
#
# 📊 Reserved Instance Opportunity
#    Switching to Reserved Instances could save $45K/month (18% reduction)
#    Impact: High - Significant cost savings
#    Recommended Action: Review RI commitment recommendations
```

**Acceptance Criteria**:
- [ ] Insight engine generates persona-specific insights
- [ ] 4+ persona types supported (CFO, Engineer, Finance, Business Lead)
- [ ] Notification system routes alerts to correct channels
- [ ] Slack and email channels working
- [ ] Alert templates for each persona

      version = "~> 1.0"
    }
  }
}

provider "openfinops" {
  endpoint = "http://openfinops.company.com"
  token    = var.openfinops_token
}

# Budget
resource "openfinops_budget" "ml_training" {
  name   = "ML Training Budget"
  amount = 50000
  period = "monthly"

  filters = {
    service     = "ml-training"
    environment = "production"
  }

  alerts {
    threshold = 80
    channels  = ["slack"]
  }
}

# Policy
resource "openfinops_policy" "gpu_approval" {
  name    = "GPU Instance Approval"
  enabled = true

  condition = <<-EOT
    resource.type == "ec2_instance" AND
    resource.instance_family IN ["p4", "p5"]
  EOT

  action {
    type      = "require_approval"
    approvers = ["cto@company.com"]
  }
}

# Data source - Query current costs
data "openfinops_cost" "ml_training" {
  filters = {
    service = "ml-training"
  }
  time_range = "30d"
}

output "ml_training_cost" {
  value = data.openfinops_cost.ml_training.total
}
```

**Testing**:
```bash
# Run acceptance tests
TF_ACC=1 go test ./... -v -timeout 120m
```

**Acceptance Criteria**:
- [ ] Terraform provider published to registry
- [ ] 5+ resource types implemented (Budget, Policy, Tag Rule, etc.)
- [ ] 3+ data sources implemented (Cost, Recommendation, etc.)
- [ ] Full CRUD operations for all resources

## 📝 Documentation Standards

### Docstring Format (Google Style)

```python
def generate_insights(
    self,
    persona: str,
    time_range: str = "30d",
    filters: Optional[Dict[str, Any]] = None
) -> List[Insight]:
    """Generate persona-specific insights.

    Args:
        persona: Target persona (cfo, engineer, finance, business_lead)
        time_range: Time range for analysis (e.g., "30d", "90d")
        filters: Optional filters for cost data

    Returns:
        List of generated insights for the persona

    Raises:
        ValueError: If persona is not recognized
        RuntimeError: If insight engine is not initialized

    Example:
        >>> engine = InsightEngine(hub=hub, cost_obs=cost_obs)
        >>> insights = engine.generate_insights(persona="cfo", time_range="30d")
        >>> for insight in insights:
        ...     print(insight.title)
    """
    pass
